    摘 要:大规模风电并网会严重影响电力系统的稳定运行及安全。分析了不同种类储能系统特性的情况,提出在系统内配置由超级电容器、电池储能以及抽水蓄能构成的复合储能系统,充分利用电池和超级电容器充放电较迅速的特点以平抑风电功率波动,利用抽水蓄能机组调节容量大的特点进行削峰填谷,以获得最小系统总成本为目标,对该复合储能系统的配置容量进行优化。以改进的IEEE RTS-96系统为例,并基于国内某风电场的历史出力数据,进行了仿真计算分析。仿真结果验证了该复合储能模型及其容量优化方法的有效性,在一定程度上提高了风电的渗透率以及系统的运行经济性。

    Abstract: Large-scale wind power integration brings adverse effects to system’s steady operation and security. This paper analyzed the conditions of different kinds of energy storage systems characteristics, proposed to configure a hybrid energy storage system (HESS) composed of super capacitor (SC), battery energy storage system (BESS) and pumped storage power station, took full advantage of the rapid charge-discharge characteristics of batteries and super capacitor to stabilize the wind power fluctuation and made use of large pump storage group adjusting capacitor characteristics to carry out peak clipping and filling valley, so as to get the target of minimum system total cost, which optimized the configuration capacity of HESS. Taking the improved IEEE RTS-96 system for example and based on the historical contributing data of certain domestic wind power plant, computational analysis was carried out simulation. The results prove the effectiveness of the proposed method and it can improve the penetration of wind power and the power system operating economy.
    Key words: battery energy storage; hybrid energy storage system; pumped storage power station; super capacitor; wind generation
